Abstract

This paper proposes a new fast adaptive motion estimation algorithm based on H.264. It utilizes the statistics of video sequence and the correlations of SADs in the space to early terminate the search, determines the search pattern according to the block's local motion activity, and proposes a new synthetic diamond search pattern. Compared to fast full search, the PSNR is just 0.017db lower and bitrates is 0.45% higher while the speed is 15 times up.
